Question

Perform the following operation and express the answer in scienfific notation 7.5x10 ^9 - 2.5 x 10^8

Answer 1

The answer is in scientific notation 34^67 42’063 1220.

The correct form for scientific notation is a x 10^b. where a is a number or decimal such that the absolute value of a is greater than or equal to 1 and less than 10, or 1 ≤ |a|. < 10. b is the power of 10 required to make the scientific notation mathematically equivalent to the original number.

To write this number in scientific notation, you must first shift the number of decimal places from the original number by 4 places between 4 and 2. We're subtracting from the exponent because we're shifting the decimal four places to the right.
